This API lets you generate external IDs manually which can be tagged to a customer while registering. A unique external ID is generated every time you call this API. The maximum allowed character is 50.

When a customer is registered without an external ID, this API is called in the back end and the unique external ID is tagged to the customer automatically. However, it does not override the existing external ID.
